Abstract

The influence of C and B micro-alloying elements on the microstructures and mechanical properties for high Nb containing TiAl alloy was systematically studied. The B micro-addition has a weak effect on the strengthening, but ribbon, or dot-shaped TiB₂ forms at the lamellar colony boundaries and refines the original colony, which is beneficial to improve the room temperature ductility of high Nb containing TiAl alloy. The precipitation of a large amount of Ti₃AlC raises the creep resistance during long time creep for high Nb containing TiAl alloy with micro-addition of C.
